Anyway, after installing the 2 new 512 mb modules my computer boots up, windows briefly starts ( I get the "Windows is starting up" prompt) and then the computer abruptly restarts itself. This will basically keep happening over and over unless I manually shut my computer off. When I removed the 2 new memory modules the computer ran normal. One time I tried to start the computer in safe mode with the new memory. It seemed to boot up normally until a blue screen appeared advising me to turn off ACPI mode. Hmmmm?
Lastly, I have heard it is advisable to download the new BIOS update before installing memory. I went on the official Sony site and there indeed does seem to be a bios update available for my model computer. Is the BIOS really what is causing my memory problems? The Data Memory Systems website claimed the memory module was 100% compatible with my make/model computer.....could it not be? I'm a little worried about installing a new BIOS, looks like it could really screw up my computer, which has been running pretty well in the last year or so? What does this sound like????
One last thing, I have installed memory modules before on my old VAIO without any problems. Thanks in advance for your replies....
